WiMax Gets Serious

Major infrastructure equipment players like Alcatel SA (NYSE: ALA; Paris: CGEP:PA) and Siemens Information and Communication Mobile Group are plotting moves into the nascent WiMax market in 2005 using silicon from Intel Corp. (Nasdaq: INTC).

Startups, smaller gear vendors, and wireless ISPs aren't waiting for the big boys but are plowing ahead with nearly-WiMax equipment and services now -- in just the same way vendors started to offer wireless LAN equipment based around the 802.11g (54 Mbit/s over 2.4GHz) standard months before that was ratified.

WiMax -- or 802.16a to its friends -- is the new hip term to drop in wireless circles [ed. note: WiFi is soooo last year, dahlink]. Fans of WiMax claim that the technology -- which is intended to provide high-speed data services over distances of 30 miles or so -- will replace everything from 3G cellular networks to DSL and wireless LAN, and still cook you breakfast in the morning.

Tigard, Ore.-based wireless ISP VeriLAN Inc. is claiming to be one of the first operators in the U.S. to offer a fixed wireless service using a WiMax-like service -- in the Portland area -- using equipment from Canadian vendor Wi-LAN Inc. (Toronto: WIN).

VeriLAN can't actually brand its service with the WiMax name yet, because the WiMax Forum won't ratify the first specification to bear that name until the summer.

"It's 99 percent there," Steven Schroedl, the president of VeriLAN told Unstrung. "But the forum doesn't want anyone using the name yet."

As well as Wi-LAN, Intel partner Alvarion Ltd. (Nasdaq: ALVR) and Redline Communications Inc. have recently introduced WiMax-ish kit.

Joe English, WiMax campaign manager at Intel, doesn't seem too worried about any problems with pre-WiMax kit coming onto the market before the real deal is ratified.

"It very much resembles what this specification will eventually become," English says. The difference is that the WiMax Forum will undertake interoperability testing between different WiMax-branded kit.

What seperates equipment from the smaller firms and upcoming gear from the likes of Alcatel is that Alvarion and others will produce kit intended as wireless cable replacement subscriber boxes, while the Gallic Gargantua's products will be targeted at the carrier market, English reckons.

Intel is due to launch its first WiMax silicon in the second half of this year, and English looks for the first WiMax-certified products to follow in early 2005. Alcatel and Siemens are plotting product for the second half of next year.

Of course, this being wireless, the terminology that describes the underlying technology just has to be confusing. Intel's first chips will actually be based on the 802.16a revision d specification, which is intended for fixed wireless applications. After that will follow silicon based on the 802.16a revision e specification, which is aimed at mobile wireless applications where battery life is a concern. According to Intel's English, some people call 802.16a rev d "802.16d... for shorthand."

Clear as mud, eh, readers?

re: WiMax Gets Serious
.....the hype is not.

30 mile reach is probably the first irrelevant item to be toned down. My car also says 260 km/h at the extreme end of the speed dial.

The eagerness of VeriLAN's President to attach a hype label on his service, claiming "WiMAX is 99% there" makes us think about the missing 1%.

Could it be that the actual interoperability testing of ANY equipment will not take place until later in the year?

Could it be that VeriLAN's vendor, Wi-LAN, has sold "WiMAX" equipment, when the marketing department should have written "802.16a compliant equipment"?

The labels "IEEE 802.16a" and "WiMax" are not synonyms. If you want to have the difference in dollars and cents, please see the stock price of Terayon the day the firm failed DOCSIS certification of much hyped products.

The example would suggest that we are "0% there" until interoperability testing has been successfully completed, as WiMax certification is a binary outcome.

On a more philosophical note, I wonder if MS Outlook qualifies for an "Intelligent Software" label, as spellcheck suggests "Wife" for WiFi, and "Woman" for "WiMax". "Trouble and strife", as they say in London.

re: WiMax Gets Serious
Wilan holds several voting seats on WIMAX forum, and
the chair for 802.16 RevD is a WI-LAN employee.

WI-lan is very careful to avoid claiming their products are WIMAX at this time. Check their website.

Claiming 802.16a is not the same as WIMAX which is likely to be a very narrow subset of 802.16a 's range of possible implementations ( single thru 256 ofdm sub carriers thru 2048 in a "onewayish" mode)

"WiMAX ... will replace everything from 3G cellular networks to DSL and wireless LAN"

What a dream! WiMAX has zero chance...

For mobile users, there is CDMA2000 EV-DO with near-DSL speed. And there is CDMA2000 EV-DV with faster speed coming on the horizon. Both without having to purchase expensive new frequency bands and folklift upgrade to existing base stations. If you are thinking about deploying WiMAX with unlicensed bands, be prepared for interference battles with other WISPs.

To compete with land lines, forget it. The incumbents DSL and cable will put up a big fight. DSL is already down to less than $30 a month. WISPs need to beat that. That means WiMAX modems must compete with $40 cable/DSL modems. Can Intel and Fujitsu WiMAX chipset beat that? Not for quite a while.

Oh, there are also WiFi hotspots competing for the mobile market too.

So what is left for WiMAX? Up the mountains and remote wilderness!

"Could it be that VeriLAN's vendor, Wi-LAN, has sold "WiMAX" equipment, when the marketing department should have written "802.16a compliant equipment"?"

You should not post things if you don't know the facts. Wi-Lan doesn't offer hype. The Vendor Verilan (and other vendors) should watch what they say in public imho.

Wi-Lan does say that there "LIBRA Series Products Provide WiMAX W-OFDM Performance and Assurance of a Seamless Transition to WiMAX Compliant Products"
http://www.wilan.com/news/pres...

To offer "WiMAX-like performance" is something different then Redline saying that your product is "...the world's first WiMAX standards-based broadband wireless system and was released in October 2003."

re: WiMax Gets Serious
"near DSL speed" ?? you must be joking. The pre Wimax Libra Wilan products are delivering 2 - 22Mbps without nlos problems.

"Near DSL" might on a good day be, what, 256kbps, and in a Manhattan canyon 2kbps?

"Forklift" you say? the base stations are about the size of a case of beer. The CPE is about the size of a computing text book ( say 5-10 cm thick).

How do i know? I've seen them first hand and with an amazing demo re the nlos stuff. Check out WI-lans recent AGM webcast.

You might be right in needing a forklift to remove the 3g and power generation equipment though.

Which 3g "standard" do you believe is real? TD-SCDMA, CDMA2K, W-CDMA..., UMTS

re: WiMax Gets Serious
I agree that the practical data rate is always below the spec data rata. CDMA2000 EV-DO doesn't give you 2.4 Mbps, but DSL doesn't give you 1.5 Mbps either.

We can argue all day long which technology is better in terms of speed and equipment size. Let's put the speed issue aside. The most important decision factor to deploy an alternative broadband technology is cost. For wireless broadband deployment, the major cost item is frequency band. The only guys who can afford it are the Verizon, Sprint, etc. because they already own the PCS and other frequency bands. For them, the wireless data revenue is a miniscule percentage. CDMA2000 is an easy migration path. Why should they deploy WiMAX?

re: WiMax Gets Serious
I think the real losers here are wireless operators who have invested a lot of money. The business model only makes sense if you can somehow boast your ARPU.

When WiMAX-type services are available, the only business model operators will be able to sell is all-you-can-eat for a little more than DSL because of wireless ubiquity (maybe up to $40/month).

EV-DO and WCDMA base stations only go about 1.5 km. Compare this to 30 km for WiMAX and the business model makes a lot of sense.

Spectrum? How about all the MMDS spectrum that's empty (I think Sprint and Nextel own most of it now).

I think this could be major and the reason is price and near-cellular ubiquity.

re: WiMax Gets Serious
Thanks for useful information.

You are a little quick to assume I say things I do not know. I pointed to the Wi-Lan customer's liberal use of terms, and raised a question about the source. As you point out, WiLan -- in its legal department reviewed PR -- is diligently distinguishing between the certified equipment and equipment marketed pre-compliance testing.

How come you did not comment on the 30-mile radius? After all, if the customers already think it will be NLOS from one side of NYC to the other to a user terminal on street level or in an office on the ground floor, at full system load, then is that good for business?

WiMax does not need the usual performance padding to be good. If the industry wants to be taken seriously, it needs to set realistic expectations about deployment parameters.

"You are a little quick to assume I say things I do not know. I pointed to the Wi-Lan customer's liberal use of terms, and raised a question about the source...."

Maybe you do "know" but i can not find it in your msg. You stated that Wi-Lan has "sold "WiMAX" equipment" knowing that they are selling "Wi-Max-like" equipment (like i said): "Could it be that VeriLAN's vendor, Wi-LAN, has sold "WiMAX" equipment, when the marketing department should have written "802.16a compliant equipment"?"

You also ask me why i don't comment on the 30 mile radius? "How come you did not comment on the 30-mile radius?"....as if i should comment on everything you print in your msg? Plus am not a real tech trond....

Various Wi-Lan products with different specs (incl. miles radius).
http://www.wilan.com/products/...

I don't know what kind of miles radius Wi-Lan's WiMax Products are going to offer. What about competitors?

Wi-Lan has stated before that there is a big difference between Near-LOS and NLOS.
http://www.bbwexchange.com/sto...

"After all, if the customers already think...."

What to say and think about what customers "think"?

IEEE 802.16 Session #30 Report

Summary
Session #30 of the IEEE 802.16 Working Group on Broadband Wireless Access took place on 15-18 March 2004 in Orlando, FL, USA, along with the IEEE 802 Plenary Session. The site was the Hilton in the Walt Disney World Resort. The attendance of 221 people, almost double that of the previous Plenary Session, broke the 802.16 record of 211, set at Session #10. Working Group membership grew from 65 to 90. In spite of the growth, broad consensus emerged on major issues.

Revision of IEEE Standard 802.16 Passes Sponsor Ballot, pending Recirculation
IEEE P802.16-REVd, a comprehensive draft revision of IEEE Standard 802.16 ("Air Interface for Fixed Broadband Wireless Access Systems") and its two amendments, completed Sponsor Ballot before Session #30. Following comment resolution during the session, only one disapprove vote remained. The 802 LMSC EC agreed, conditionally, to forward the draft for IEEE-SA approval. The Working Group intends to submit the draft in May, following recirculation. Once approved, the document will be published as IEEE Standard 802.16-2004 and will replace IEEE Standards 802.16-2001, 802.16c-2002, and 802.16a-2003.

Mobile WirelessMAN (P802.16e) Draft Finishes Working Group Letter Ballot
A Working Group Letter Ballot was completed regarding IEEE P802.16e/D1, the first draft of the enhancement of the WirelessMAN air interface to support mobile as well as fixed users. During the session, comments were resolved. Since the ballot concluded successfully, a recirculation of comments will be initiated.
